SPECIFICATION forming part of Letters Patent No. 349,530, dated September 21, 1886. Application filed June 19, 1886. Serial No. 205,637. (No specimens.)

,To all whom it may concern:

Be it known that we, ISAAC SHERCK and JOSEPH BATIG, J r., of Fremont, in the county of Sandusky and State of Ohio, have invented certain new and useful Improvements in Methods of \Vaxing Paper; and we do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it ap- I'o pertains to make and use the same.

Our invention relates to an improvement in the method of waxing paper.

The object is to saturate the paper in large quantities and remove the surperfluous wax therefrom without removing the paper from the tank within which it is saturated.

Vith this end in View our-invention con sists in placing a roll or quantity of paper in a tank of melted wax below the surface of thewax, thoroughly impregnating the paper by the application of heat, and stripping and smoothing the surface of the paper before it leaves the tank.

A device for carrying out our process is rep- 2 5 resented in the accompanying drawing in transverse section.

A represents a tank, preferably provided with a rounded bottom, a, and supported over a fire-chamber, radiating coils, or hot-air or steam box, B, by means of which the wax which is placed in the tank may be brought to a boiling-heat. YVithin the tank is a pair of depending standards or slings, 0, adapted to suspend a shaft, D, on which a roll of pa- 5 per, E, is slipped,near the bottom of the tank, or below the surface of the wax within the tank. The standards 0 are preferably provided with ball-bearings c, to admit of a free rotary movement of the shaft D, and to pre- 0 vent wear. The standards or slings O are also adapted to be, readily removed from within the tank to adjust a new roll of paper.

Along one side of the tank are strippers or smoothers F, G, and H, arranged in pairs, as

5 shown, having their lower edges beveled to turn the superfluous wax away from the paper, and their upper edges hollowed out, as shown at f and g, to catch the wax which may fallfrom the strippers located above them, or

which may tend to travel downwardly along the sides of the paper and conduct it back into the tank at one end out of engagement with the paper. The upper Set of strippers or smoothers, H, is conveniently located at the top of the tank, and one of the said pair-the one toward the middle of the tankis hinged to the cover I and adapted to be swung away from its mate when the cover is raised. The inner one of each of the other sets of strippers is also removable to admit of the adjustment of a new roll of paper. They may be singly removable, or they may be attached to a removable frame, as shown. They'are further provided with means for adjusting them towardand away from their mates to regulate the tension. Set-screws i are found convenient for this purpose. The upper inner stripper or smoother is provided with a spiral spring, K, attached to its upper edge and to the cover, the tension of which tends to hold the edge of the smoother in contact with the paper. The tension of the spring K may be varied by means of 'a pin or screw, 70, working in a seriesof perforations in the cover, or in any otherapproved manner. The tank is preferably constructed with one side higher than the other, and the coveris hinged to the lower side. One or a pair of set-screws are attached to the cover and serve to adjust it up and down,and thereby press thestripper or smooth- 8o er pad hingedthereto into lighter or closer contact with the paper. A pair of synchronously-geared rolls, L, are located within the tank just beneath the upper pair of strippers or smoothers, and serve to draw the paper from the roll through the sets of strippers beneath it. A reel, M, above the tank receives the paper from the upperstri ppers or smoothers, H.

The device hereinabove described is a very 9o convenient form for carrying out our improved method, and is reserved as the subject-matter of a separate application. The paper is placed in the melted wax, a whole roll at a-time, and the wax is thoroughly incorporated therein by heating the wax to a boiling-heat. It is then draw out from the tank between the several sets of strippers or smoothers and wound directly on a reel in a finished state.

\Ve are aware that it is not broadly new to immerse a quantity of paper in melted wax, and also that it is old to carry a strip of paper under a roller submerged in melted'wax, and from thence between scrapers located out- 5 side of the tank containing the melted wax, and hence we make no claim, broadly, to such constructions.

Having fully described our invention, what we claim as new, and desire to secure by Letters TO Patent, is-- 1. The method of waxing paper, consisting, essentially, in placing a quantity of paper in melted wax, incorporating the wax with the paper by heating the wax and finishing the 15 surface of the paper within the tank of wax.
